ABSTRACT:
Disclosed are thermally curable compositions comprising at least one cyclic ether, an initiator selected from the group consisting of an iodonium salt, a sulfonium salt, an acylium salt, a tropylium salt, an oxonium salt, and combinations thereof, and a catalyst having structure Pd(Q)2, wherein Q is at least one ligand selected from the group consisting of a carboxylate, a halide, a ketoester, an ester, a ketone, an hydroxyl, and combinations thereof. Disclosed also are methods of curing the thermally curable compositions, and articles made therefrom. Curing methods comprise heating the composition to a suitable temperature for a period of time. Articles may comprise coated articles, shaped articles or shaped components. Compositions and methods may also be used for composite repair applications.
